摘要:

以4,5-二甲氧基-2-氨基苯甲酸和醋酸甲脒为原料, 经环化、 氯化、 胺化和缩合反应, 合成了15个新的喹唑啉哌嗪缩氨基硫脲衍生物, 其结构经1H NMR, 13C NMR, HRMS及元素分析确认. 采用MTT法测试了化合物6a~6o对表皮生长因子受体(EGFR)过度表达的人乳腺癌MCF-7、 人肺癌A549和人前列腺癌PC3的体外抗癌活性. 结果表明, 部分化合物表现出较强的抗癌活性, 其中, 化合物6a和6o对3种癌细胞的抗癌活性优于对照药拉帕替尼(Lapatinib), 略低于对照药阿霉素(ADM). 化合物6a和6o对MCF-7的IC50值分别为6.97和6.99 μmol/L, 对A549的IC50值分别为5.15和3.11 μmol/L, 而对PC3的IC50值分别为2.30和1.42 μmol/L. 本文还初步探讨了化合物结构与抗癌活性之间的关系.

Abstract:

To find new EGFR inhibitors, 15 novel quinazoline derivatives containing thiosemicarbazone structure were designed and synthesized from 2-amino-4,5-dimethoxybenzoic acid and formamidine acetate by the cyclization, chlorination, amination and condensation reactions. All structures of target compounds were confirmed by 1H NMR, 13C NMR, HRMS and elemental analysis. The in vitro anticancer activities of compounds 6a—6o against EGFR over-expressing of MCF-7(Human breast cancer), A549(Human pulmonary adenocarcinoma) and PC3(Human prostate cancer) cell lines were tested using colorimetric MTT assay. The results indicated that several compounds showed potent activity. Compounds 6a and 6o were more potent than Lapatinib, but slightly weaker than ADM against the three cell lines. The IC50 values of compounds 6a and 6o against MCF-7 cell line were 6.97 and 6.99 μmol/L, against A549 were 5.15 and 3.11 μmol/L and against PC3 were 2.30 and 1.42 μmol/L, respectively. Preliminary structure-activity relationship was also discussed.
